Title: Color compression system for color picture
Inventor: YOSHIDA MICHIKO
IPC: G09G5/02
Filed: 1992-09-09
Abstract: PURPOSE:To obtain a picture with high picture quality independently of a hue even when color reproduction density is limited by employing a color coordinate space and applying nonlinear compression to a lightness and a saturation that takes a characteristic of the color coordinate system and a characteristic of an output device into account. CONSTITUTION:A data input section 1 reads a picture of an original or the like and generates color density data. A 1st color conversion section 2 converts inputted color density data into lightness.saturation.hue coordinate system (L.a.n' coordinate system or L.u.v.coordinate system or the like in the Munsell system or uniform color space coordinate system). Then converted picture data are fed to a color compression section 4 without other modification, where the color is compressed or stored in a picture database 3. Moreover, when the stored picture data are fed to the color compression section 4, the lightness and the saturation are compressed without changing the hue in a rate of reproduction available range of an output device 6. Actually the compression that takes the characteristic of the output device into account is required and since the color compression section 4 implements nonlinear compression corresponding to the characteristic, the picture with high picture quality is reproduced.

Title: Sealing material and cutting method therefor
Inventor: NOBORI KAZUNORI
IPC: B23K26/38
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution of an equipment and the adjusting of the equipment and the adjusting of a laser output without resulting in the increasing of the weight of sealing material by irradiating the sealing material in which a material through which a laser beam is allowed to pass is used as a separator with a laser beam. SOLUTION: Sealing base material 3 is cut together with adhesive material 2 by irradiating the sealing material constituted by sticking the sealing base material 3 to a separator 1 made of material through which a laser beam 9 passes with adhesive material 2 with the laser beam 9. Consequently, the sealing material 3 with the adhesive material 2 which absorbes energy of the laser beam 9 is cut into shapes having required sizes without cutting the separator 1 and strippable seals being in a state in which the seals are stuck to the separator 1 are produced. That is, the cutting of only seals is made possible with a simple control and without a delicate adjustment and also the increasing of the weight of the sealing material of its own is prevented by making the material of the separator 1 to be material through which the laser 9 passes.

Abstract: PURPOSE:To contrive accomplishment of effective utilization of superconducting energy by a method wherein the inert gas coming from a heat-insulating container is compressed, it is led to a heat exchanger, it is liquefied by cooling by using cold heat of liquefied natural gas in a heat exchanger, it returns to the heat-insulating container, and the wasteful use of the liquefied natural gas can be eliminated. CONSTITUTION:The nitrogen gas evaporated in a heat insulating container is led to a pipeline 5 by a pipeline 3b, the nitrogen gas evaporated in a supply tank 4 is collected in the pipeline 5 by a pipeline 4a, and it is led to a compressor 6 located outside a cylindrical container 1 through the pipeline 5. The nitrogen gas compressed by the compressor 6 is sent to the pipe of a heat exchanger 7 through a pipeline 8a. By sending the liquefied natural gas to the heat exchanger 7, the cold heat of the liquefied natural gas is moved to the nitrogen gas, and the nitrogen gas is liquefied by cooling. The liquefied nitrogen gas by the heat exchanger 7 returns again to the supply tank 4 in the container 1 through the pipeline 8b. As a result, the wasteful heat generation of the liquefied natural gas is eliminated, and the effective utilization of the liquefied natural gas can be accomplished.
